After finishing school, Rühlmann attended the technical college in Dresden from 1829 . In 1835 he took a position here as an assistant mathematics teacher, in 1836 he went to the royal trade school in Chemnitz as a full teacher of applied mathematics . In 1837/38 he made several trips a. a. to France, Belgium and Switzerland to gain knowledge about the industry there. He then became a technical advisor in customs and privilege matters in 1838. In 1840 he received his doctorate at the University of Jena and was appointed professor of applied mathematics and mechanical engineering at the higher trade school in Hanover. One of his students there was Franz Frese .
While teaching in Dresden, he began to write specialist books on mechanics and machine science. He is considered to be the founder of the historical school of technology.
In 1846 Rühlmann received the honorary citizenship of the city of Hanover (at the same time as Friedrich Heeren , Karl Karmarsch and Heinrich Kirchweger ). On May 1, 1856, the Landsmannschaft Slesvico-Holsatia, later the Corps Slesvico-Holsatia , awarded him the ribbon. Later he also received the ribbon of the Corps Saxonia Hannover .
